Moments later, Diamond came close to extending the Hosts’ lead but saw his effort well stopped by Maynard-Brewer.

The midfielder again came close to getting his name on the scoresheet just after half time, but his effort skewed just wide of the left-hand post.

Diamond finally got the goal his performance deserved in the 56th minute when he fired in powerful effort from the edge of the box.

With 20 minutes to go, Terrique Anderson came close to pulling a goal back for Charlton. Cutting in from the left and finding space on the edge of the box after an amazing run, but Johnstone was equal to the shot.
